If you won the lottery, what would you buy a 16 year old girl?

Everyone dreams of winning the multi million dollar jack pot right? Right! So today my Dad and I got on the topic of what he'd get me if he ever won. What would you prefer to get a 16 year old girl, a BMW M6, a Range Rover Autobiography, or a Porsche 911 Twin Turbo convertible? What would you get yourself? First Vacation? First Car? First Vacation Home etc...
